OR

The OR logic function block can evaluate the state of two integers to see if either input A or B is true. If input A OR B is true - the output C will be true (logic 1). If both input A and B are true (logic 1) - the output C will also be true (logic 1).

Input Operands A & B must be integer values: MI , SI or # constant integer value.

Output Operand C may be a Memory Integer or a System Integer.
